VENTING INTRODUCTION
The HZ54 uses the "balanced fl ue" technology Co Axial system. The
inner liner vents products of combustion to the outside while the outer
liner draws outside combustion air into the combustion chamber thereby
eliminating the need to use heated room air for combustion and losing
warm room air up the chimney.
Note: These fl ue pipes must not be connected to any other
appliance.
The gas appliance and vent system must be vented directly to the outside
of the building, and never be attached to a chimney serving a separate solid
fuel or gas burning appliance. Each direct vent gas appliance must use
it's own separate vent system. Common vent systems are prohibited.

RIGID PIPE VENTING SYSTEMS
INSTALLATION
BASIC HORIZONTAL & VERTICAL TERMINATIONS
Rigid Pipe Vent Systems offer a complete line of
component parts for installation of both horizontal
and vertical installations. Many items are offered in
decorative black, as well as galvanized fi nish.
The minimum components required for a basic
Horizontal Termination are:
1 AstroCap XL Termination Cap
1 90o Elbow
1 Rigid Pipe Adaptor
1 Wall Thimble
1 Length of rigid pipe to suit wall thickness
The minimum components required for a basic
Vertical Termination are:
1 Vertical Termination Cap
1 Rigid Pipe Adaptor
1 Lengths of pipe to adequately
penetrate roof
1 Ceiling Firestop
1 Flashing
1 Storm Collar
Wall thickness is measured from the back
standoffs to the inside mounting surface of
termination cap. For siding other than vinyl furring
strips may be used, instead of the vinyl siding
standoff, to create a level surface to mount the
vent terminal. The Terminal must not be recessed
into siding. Measure the wall thickness including
furring strips.
INSTALLATION
If a Vinyl Siding Standoff is required (it must be
used with vinyl siding), measure to outside surface
of wall without siding and add 2 inches.
WARNING:
Do not combine venting components from
different venting systems.
Exception: However, use of the the AstroCap
XLTM is acceptable with all systems.
This product has been evaluated by Intertek
for using a Rigid Pipe Adaptor in conjunction
with Simpson DV Pro, Metal-Fab Sure-Seal
and Selkirk Direct-Temp systems. Use of these
systems with the Rigid Pipe adaptor is deemed
acceptable and does not affect the Warnock
Hersey/Intertek listing of components.

UNIT INSTALLATION
WITH HORIZONTAL
TERMINATION
(Rigid Vent Systems)
A top clearance of 3"(76mm) and side & bottom
clearance of 2"(51mm) must be maintained;
except when passing through a wall, ceiling, or at the termination where the use of a
INSTALLATION
fi restop or wall thimble reduces the required
clearance to 1-1/2" (38mm). We recommend
framing a 11"(279mm) x 11"(279mm) (inside
dimensions) hole to give structural rigidity
for mounting the termination.
Install the vent system according to the
manufacturer's instructions included with the
components.
1) Set the unit in its desired location. Check to
determine if wall studs or roof rafters are in
the way when the venting system is attached.
If this is the case, you may want to adjust
the location of the unit. Rough in the gas
preferably on the right side of the unit.
2) Direct Vent pipe and fi ttings are designed with
special twist-lock connections to connect the
venting system to the appliance fl ue outlet.
A twist-lock appliance adaptor is required.
3) In conjunction with the Simpson Direct Vent
Pro system, install the adaptor after the unit is
set in its desired location. Put a bead of high
temperature silicone inside the outer section
of the adapter and a bead of Mill Pack on the
inner collar. Slip the adapter over the existing
inner and outer fl ue collar. Fasten to the outer
collar only with the 3 supplied screws (drilling
pilot holes will make this easier).
4) Level the fi replace and fasten it to the framing
using nails or screws through the top and
side nailing strips.
5) Assemble the desired combination of pipe
and elbows to the appliance adaptor and
twist-lock for a solid connection.
Note: For best results and optimum
performance with each approved
venting system, it is highly
recommended to apply “Mill-Pac”
sealant (supplied) to every inner pipe
connection. Failure to do so may result
in drafting or performance issues not
covered under warranty. Silicone (red
RTV) is optional.
Diagram 1
Horizontal runs of vent must be supported
every 3 feet (0.9meter). Wall straps are
available for this purpose.
6) Mark the wall for a 11" x 11" (279mm x
279mm) square hole. The center of the
square hole should line up with the centerline of the horizontal pipe. Cut and frame the
11 inch (279mm) square hole in the exterior
wall where the vent will be terminated. See
diagram 2 for center line requirements.
If the wall being penetrated is constructed of
non-combustible material, i.e. masonry block
or concrete, an 8" (203mm) diameter hole
is acceptable.
Diagram 2
Note:
a) The horizontal run of vent must be level,
or have a 1/4 inch rise for every 1 foot
of run towards the termination. Never
allow the vent to run downward. This
could cause high temperatures and may
present the possibility of a fi re.
b) The location of the horizontal vent
termination on an exterior wall must meet
all local and national building codes, and
must not be blocked or obstructed. See
"Exterior Vent Termination Locations"
section for more details.
7) Ensure that the pipe clearances to
combustible materials are maintained
(Diagram 5). Install the termination cap.
Note: If installing termination on a vinyl
siding covered wall, a vinyl siding
standoff or furring strips must be used
to ensure that the termination is not
recessed into the siding.
Diagram 5
The four wood screws provided should be re-
placed with appropriate fasteners for stucco,
brick, concrete, or other types of sidings.
8) Before connecting the horizontal run of vent
pipe to the vent termination, slide the Wall
Thimble over the vent pipe. The wall thimble
is required for all horizontal terminations.
9) Slide the appliance and vent assembly
towards the wall carefully inserting the vent
pipe into the vent cap assembly. It is important
that the vent pipe extends into the vent cap
suffi cient distance so as to result in a minimum
pipe overlap of 1-1/4 inches (32mm). Secure
the connection between the vent pipe and
the vent cap.
10) Install wall thimble in the center of the 11"
(279mm) square and attach with wood screws
(Diagram 7).

UNIT INSTALLATION
WITH VERTICAL
TERMINATION
(Rigid Vent Systems)
Note: A clearance of 2"(51mm) must be
maintained; except when passing
through a wall, ceiling, or at the
termination where the use of a fi restop
or wall thimble reduces the required
clearance to 1-1/2" (38mm). We
recommend framing a 11"(279mm) x
11"(279mm) (inside dimensions) hole
to give structural rigidity for mounting
the termination.
1) Maintain the 1-1/2" (38mm)
clearances (air spaces)
to combustibles when
passing through ceilings,
walls, roofs, enclosures,
attic rafter, or other nearby
combustible surfaces,
ensuring that the use of
a firestop or wall thimble
is used as noted above.
Do not pack air spaces
with insulation. Check
"Venting Arrangemnt
- Vertical Termination"
section for the maximum
vertical rise of the venting
system and the maximum
horizontal offset
limitations.
2) Set the gas appliance
in its desired location.
Drop a plumb bob
down from the ceiling
to the position of the
appliance fl ue exit,
and mark the location
where the vent will
penetrate the ceiling.
Drill a small hole at
his point. Next, drop
a plumb bob from
the roof to the hole
previously drilled in the ceiling, and mark the
spot where the vent will penetrate the roof.
Determine if ceiling joists, roof rafters or other
framing will obstruct the venting system. You
may wish to relocate the appliance or to offset,
as shown in Diagram 2 to avoid cutting load
bearing members.
3) A Firestop spacer must be installed in the fl oor
or ceiling of every level.
Diagram 3
Diagram 1
Diagram 2
4) Assemble the desired lengths of pipe and
elbows. Ensure that all pipes and elbow
connections are in the fully twist-locked
position and sealed.
Note:
For best results and optimum performance
with each approved venting system, it is
highly recommended to apply “Mill-Pac”
sealant (supplied) to every inner pipe connection. Failure to do so may result in drafting
or performance issues not covered under
warranty. Silicone (red RTV) is optional.
5) Cut a hole in the roof centered on the small
drilled hole placed in the roof in Step 2. The
hole should be of suffi cient size to meet
the minimum requirements for clearance to
combustibles of 1-1/2"(38mm). Slip the fl ashing
under the shingles (shingles should overlap
half the fl ashing) as per Diagram 4.
Diagram 4: The upper half of the fl ashing is
installed under the roofi ng material and not
nailed down until the chimney is installed.
This allows for small adjustments.
6) Continue to assemble pipe lengths.
Note: If an offset is necessary in the attic
to avoid obstructions, it is important
to support the vent pipe every 3
feet (0.9 meter), to avoid excessive
stress on the elbows, and possible
separation. Wall straps are available
for this purpose
(Diagram 2).
Galvanized pipe is desirable above the roofl ine
due to its higher corrosion resistance. Continue
to add pipe sections through the fl ashing until
the height of the vent cap meets the minimum
height requirements specifi ed in Diagram 5 or
local codes. Note that for steep roof pitches,
the vertical height must be increased.
Diagram 5

over 18/12 to 20/12 7.5 2.29
A poor draft, or down drafting can result from
high wind conditions near big trees or adjoining
roof lines, in these cases, increasing the vent
height may solve the problem.
7) Ensure vent is vertical and secure the base
of the fl ashing to the roof with roofi ng rails,
slide storm collar over the pipe section and
seal with a mastic.
8) Install the vertical termination cap by twist-
locking it.
Note: Any closets or storage spaces, which
the vent passes through must be
enclosed.

HORIZONTAL TERMINATION
WITH FLEX VENT SYSTEM
Note: A top clearance of 3"(76mm) and
side & bottom clearance of 2"(51mm)
must be maintained; except when
passing through a wall, ceiling, or
at the termination where the use of
a fi restop or wall thimble reduces the
INSTALLATION
required clearance to 1-1/2" (38mm).
We recommend framing a 11"(279mm)
x 11"(279mm) (inside dimensions)
hole to give structural rigidity for
mounting the termination.
1) Locate the unit in the framing, rough in the
gas (preferably on the right side of the unit).
Locate the centerline of the termination and
mark wall accordingly. Cut an 11"(279mm)
hole in the wall (inside dimension).
4) Separate the 2 halves of the wall thimble and
securely fasten the one with the tabs to the
outside wall making sure that the tabs are
on top and bottom. Fasten the other thimble
half to the inside wall. The thimble halves
slip inside each other and can be adjusted
for 2 x 4 or 2 x 6 walls.
5) Slip the assembled liner and termination
assembly through the thimble making sure
the termination cap faces up (there are
markings on the cap that show which way
is up). This will position the termination cap
with proper down slope for draining water.
Fasten the cap to the outer wall with the 4
supplied screws.
6) Pull the centre 5"(127mm) liner and outer
8"(203mm) liner out enough to slip over
the fl ue collars of the fi replace. (You may
wish to cut the liner shorter to make it more
workable.) Do not bend liner more than 90
The liners must slip over the collars a
minimum of 1-3/8".
7) Apply Mill Pac over the fi replace inner collar
and slip the 5"(127mm) liner down over it
and attach with 3 supplied screws.
8) Do the same with the 8"(203mm) liner.
o
IMPORTANT: Do not locate termination
hood where excessive snow or ice
buildup may occur. Be sure to check vent
termination area after snow falls, and clear
to prevent accidental blockage of venting
system. When using snow blowers, make
sure snow is not directed towards vent
termination area.

Note: If installing termination on a siding
covered wall, a vinyl siding standoff
or vinyl furring strips must be used
to ensure that the termination is not
recessed into the siding.
2) Level the fi replace and fasten it to the fram-
ing using nails or screws through the nailing
strips.
3) Assemble the vent assembly by applying
Mill Pac to the 5"(127mm) inner collar of
the termination and slipping the 5"(127mm)
liner over it at least 1-3/8" (35mm). Fasten
with the 3 screws (drilling pilot holes will
make this easier). Apply Mill Pac or high
temperature silicone to the 8"(203mm) fl ex
pipe and slip it over the 8" outer collar of
the vent terminal at least 1-3/8"(35mm) and
fasten with the 3 screws.
NOTE: Horizontal sections must be sup-
ported at intervals not exceeding 3
feet (0.9 meter). (Flame picture and
performance will be affected by sags
in the liner).
9) Apply a bead of silicone between the thimble
and termination and around the outer edge
of the terminal at the wall in order to keep
the water out.

HIGH ELEVATION
This unit is approved for altitude 0 to 4500 ft.
(CAN1 2.17-M91).
GAS LINE
INSTALLATION
Since some municipalities have additional
local codes it is always best to consult with
your local authorities and the CAN/CGA B149
installation code.
For USA installations follow local codes and/or
the current National Fuel Gas Code, ANSI
Z223.1.
When using copper or fl ex connectors use only
approved fi ttings. Always provide a union so
that gas lines can be easily disconnected for
servicing. Flare nuts for copper lines and fl ex
connectors are usually considered to meet this
requirement.
NOTE: A shutoff / dante valve should be supplied in or near the unit (or as per local codes)
for ease of servicing this appliance.
IMPORTANT: Always check for gas leaks
with a soap and water solution or gas leak
detector. Do not use open fl ame for leak
testing.
PILOT ADJUSTMENT
Periodically check the pilot fl ames. Correct
fl ame pattern has three strong blue fl ames:
1 fl owing around the thermopile, 1 around
the thermocouple and 1 fl owing across the
burner (it does not have to be touching the
burner).
Note: If you have an incorrect fl ame pattern,
contact your Regency® dealer for
further instructions.
Incorrect fl ame pattern will have small,
probably yellow fl ames, not coming into
proper contact with the rear burner or
thermopile or thermocouple.
GAS PIPE PRESSURE
TESTING
The appliance must be isolated from the gas
supply piping system by closing its individual
manual shut-off valve during any pressure
testing of the gas supply piping system at
test pressures equal to or less than 1/2 psig.
(3.45 kPa). Disconnect piping from valve at
pressures over 1/2 psig.
The manifold pressure is controlled by a regulator
built into the gas control, and should be checked
at the pressure test point.
Note: To properly check gas pressure, both
inlet and manifold pressures should
be checked using the valve pressure
ports on the valve.
1) Make sure the valve is in the "OFF"
position.
2) Loosen the "IN" and/or "OUT" pressure tap(s),
turning counterclockwise with a
1/8" wide fl at screwdriver.
3) Attach manometer to "IN" and/or "OUT"
pressure tap(s) using a 5/16" ID hose.
4) Light the pilot and turn the valve to "ON"
position.
5) The pressure check should be carried out
with the unit burning and the setting should
be within the limits specifi ed on the safety
label.
6) When fi nished reading manometer, turn off the
gas valve, disconnect the hose and tighten the
screw (clockwise) with a 1/8" fl at screwdriver.
Note: Screw should be snug, but do not
over tighten.

OPTIONAL STAINLESS STEEL
REFLECTIVE PANEL INSTALLATION
INSTALLATION
Before you start:
Stainless panels must be inspected for scratches and dimples prior to installation. All claims to be recorded at this time. Claims for
damage after installation will not receive consideration.
To protect the fi nish during installation and handling - cotton gloves MUST be worn at all times while handling the panels (even
when removing protective coating).
Stainless panels will discolor a little during normal operation. This is normal and should not be considered a defect.
All hand and fi nger marks MUST be cleaned off with a soft cloth and a stainless steel cleaner. Most stainless steel cleaners leave a
fi lm/residue on the surface of the panels. Use an ammonia based cleaner (ie. glass cleaner) to remove this fi lm before applying heat to
the unit. Failure to do this will result in burn stain on panels which you will be unable to remove. This is not a warranty item.
1) Position the left side panel in place and fi t the bottom tab into the slot
at the bottom of the fi rebox as shown below. Repeat for right side
panel.

OPERATING INSTRUCTIONS
OPERATING
INSTRUCTIONS
1) Read and understand these instructions
before operating this appliance.
2) Check to see that all wiring is correct and
enclosed to prevent possible shock.
3) Check to ensure there are no gas leaks.
4) Make sure the glass in the glass door frame
is properly positioned. Never operate the
appliance with the glass removed.
5) Verify that the venting and cap are
unobstructed.
6) The unit should never be turned off, and on
again without a minimum of a 60 second
wait.
FIRST FIRE
The FIRST FIRE in your heater is part of the paint
curing process. To ensure the paint is properly
cured, it is recommended you burn your fi replace
for at least four (4) hours the fi rst time.
When fi rst operated, the unit will release an
odour caused by the curing of the paint and the
burning off of any oils remaining from manufacturing. Smoke detectors in the house may go off
at this time. Open a few windows to ventilate
the room for a couple of hours. The glass may
require cleaning.
NOTE: When the glass is cold and the appliance
is lit, it may cause condensation and fog
the glass. This condensation is normal
and will disappear in a few minutes as
the glass heats up.
DO NOT ATTEMPT TO CLEAN THE
GLASS WHILE IT IS STILL HOT!
LIGHTING
PROCEDURE
IMPORTANT
To ignite or reignite the pilot, you
must fi rst remove the glass door.
NOTE: The Gas ON/OFF knob cannot be
turned from "ON", "PILOT" or "OFF" unless
it is partially depressed.
1) Ensure the wall mounted switch or remote
is in the "OFF" position.
2) Turn the gas control knob so the indicator
points to the "OFF" position and wait 5 minutes for any gas in the combustion chamber
to escape.
3) Turn the gas control knob counterclockwise
so the indicator points to the "PILOT" position.
Depress the gas control knob fully. Depress
the igniter button until the pilot lights. After
approximately one minute, release the gas
control knob. The pilot fl ame should continue
to burn.
Only when the pilot holds, without pressure
being applied to the gas control knob, re-install
the glass door to the unit. The unit must not
be operated without the glass door in place.
If the pilot does not remain lit, repeat opera-
tion allowing a longer period before releasing
gas control knob.
4) When the pilot stays lit, turn the gas control
knob to the "ON" position.
5) Use the wall switch or remote control to turn
the unit ON.
NOTE: When using the remote control refer to
the remote manual.
NOTE: If there is no spark present at the pilot
when depressed, the AA battery may
be weak. Refer to "DC Spark Battery
Replacement" section.
NORMAL OPERATING
SOUNDS OF
GAS APPLIANCES
It is possible that you will hear some sounds from
your gas appliance. This is perfectly normal due to
the fact that there are various gauges and types
of steel used within your appliance. Listed below
are some examples. All are normal operating
sounds and should not be considered as defects
in your appliance.
Burner Tray:
The burner tray is positioned directly under the
burner and is made of a different gauge material
from the rest of the fi rebox and body. Therefore,
the varying thicknesses of steel will expand and
contract at slightly different rates which can cause
"ticking" and "cracking" sounds. You should also
be aware that as there are temperature changes
within the unit these sounds will likely re-occur.
Again, this is normal for steel fi reboxes.
Pilot Flame:
While the pilot fl ame is on it can make a very
slight "whisper" sound.
Gas Control Valve:
As the gas control valve turns ON and OFF, a
dull clicking sound may be audible, this is normal
operation of a gas regulator or valve.
Unit Body/Firebox:
Different types and thicknesses of steel will
expand and contract at different rates resulting
in some "cracking" and "ticking" sounds will be
heard throughout the cycling process.
OPERATION
DO NOT BURN THE UNIT WITHOUT THE
GLASS DOOR IN PLACE.
SHUTDOWN
PROCEDURE
During the fi rst few fi res, a white fi lm
may develop on the glass front as part of
the curing process. The glass should be
cleaned after the unit has cooled down
or the fi lm will bake on and become very
diffi cult to remove. Use a non-abrasive
cleaner and DO NOT ATTEMPT TO CLEAN
THE GLASS WHILE IT IS HOT.
HZ54 Regency HorizonTM Gas Fireplace 37
1) Turn the wall mounted switch or remote to
the "OFF" position.
2) Press "OFF" on the remote control.
3) Turn the gas control knob to the "OFF" posi-
tion to turn off the pilot.

GENERAL VENT
MAINTENANCE
Conduct an inspection of the venting system
semi-annually. Recommended areas to inspect
as follows:
1) Check the Venting System for corrosion in
areas that are exposed to the elements.
These will appear as rust spots or
streaks, and in extreme cases, holes.
These components should be replaced
immediately.
2) Remove the Cap, and shine a fl ashlight
down the Vent. Remove any bird nests, or
other foreign material.
3) Check for evidences of excessive
condensation, such as water droplets forming
in the inner liner, and subsequently dripping
out the joints, Continuous condensation can
cause corrosion of caps, pipe, and fi ttings.
It may be caused by having excessive
lateral runs, too many elbows, and exterior
portions of the system being exposed to
cold weather.
4) Inspect joints, to verify that no pipe
sections or fi ttings have been disturbed,
and consequently loosened. Also check
mechanical supports such as Wall Straps,
or plumbers' tape for rigidity.
THERMOPILE /
THERMOCOUPLE
1) Remove the valve tray by following the
procedures from "Valve Tray Replacement"
section.
2) Disconnect thermocouple by loosening
